Enrichment of Neandertal DNA.
Older Neandertal survived with a little help from his friends.
Fossil tooth pushes back record of mysterious Neandertal relative.
The skull of a Neandertal known as Shanidar 1 shows signs of a blow to the head received at an early age.
Those of us who live outside Africa carry a little Neandertal DNA in us,' says Svante Pääbo.
Over the past 150 years, Neandertal remains have been found at many sites in Europe, Asia and the Middle East.
Earlier studies had suggested that human genes involved in skin andhair biology were strongly influenced by Neandertal DNA.
Living people carry only trace amounts of Neandertal DNA, which makes its impact on health more striking.
Bohlender and his colleagues calculate that Europeans andChinese people carry a similar amount of this Neandertal ancestry- some 2.8 percent.
Recent studies have shown that some of those Neandertal genes have contributed to human immunity and modern diseases.
Other Neandertal alleles regulate the transport of thiamine, or vitamin B1, which metabolizes carbohydrates in cells of the gut.
People outside of Africa still carry a small amount of Neandertal DNA, some of which may cause health problems.
Boule concluded that Neandertal man could not have walked erectly, but rather must have walked in a clumsy fashion.
Analyses of the genome also revealed that the Denisovan father had at least one Neandertal ancestor further back in his family tree.
The researchers also found a number of Neandertal genes associated with neurological conditions, including depression, which can be triggered by disturbed circadian rhythms.
The best-known human fossils are of Cro-Magnon man(whose marvelous paintings are found on the walls of caves in France) and Neandertal man.
Akey and Capra joined forces and searched for more than 6000 Neandertal haplotypes in genetic data from 28,416 adults of European ancestry.
While many Neandertal fossils have been found in Europe and Asia, Denisovans are known only from DNA from a finger bone and a couple of teeth found in a Siberian cave.
Studies have shown that human genes involved in skin andhair biology were strongly influenced by Neandertal DNA but it hadn't been clear how.
Kelso notes that the traits influenced by Neandertal DNA, including skin and hair pigmentation, mood, and sleeping patterns are all linked to sunlight exposure.
DNA retrieved from a child's worn-down fossil tooth shows the ancient Asian roots of extinct Neandertal relatives called Denisovans, researchers say.
They found that at birth, both Neandertal andmodern human infants had elongated braincases that were similar in shape, although Neandertal faces were already larger.
It uses a powerful new method for scanning the electronic health records of 28,000 Americans to show that some Neandertal gene variants today can raise the risk of depression, skin lesions, blood clots, and other disorders.
Most of the misconceptions about Neandertal man resulted from the claims of the Frenchman Marcelin Boule who, in 1908,studied two Neandertal skeletons that were found in France(LeMoustier and La Chapelle-aux-Saints).
By using the detailed Denisovan genome to sharpen the view of their close cousins the Neandertals,the team concludes that living East Asians have more Neandertal DNA than Europeans have.
By comparing the genomes of a few Neandertals and one Denisovan with people in the 1000 Genomes database,computational biologists have recently uncovered about 12,000 Neandertal gene versions, or haplotypes, in living Europeans and Asians.
The finding fits with earlier studies that have found that although living Asians and Europeans have inherited 1% to 3% of their DNA from their ancestors' interbreeding with Neandertals,they are missing chunks of Neandertal DNA on their Y chromosomes.
Among many findings,they report that early modern human gene flow into Neandertal populations occurred between 130,000 and 145,000 years ago, before the Croatian and Siberian Neandertals diverged.
Neandertal diets, rich in meat and nuts, may have provided ample thiamine, but people munching processed foods today may not get enough, and having the Neandertal variant may predispose them to malnutrition, Capra speculates.
Viola's presentation was one of several at the meeting that raised new questions about these Neandertal relatives- including how recently they existed- who are known only from previous discoveries in Denisova Cave.
